METAL WHEEL.

ployed, said disk or plate being formed in spoke part of the wheel.

one piece with a hub part, rim part and an intervening web portion answering to the My invention is designed particularlyfor use in the construction of wheels wherein the separate rim or felly is secured to the metal disk or plate.

The object of the invention is to provide a suitable support or bearing for the rim and likewise to enable the wheel to be cheaply and easily constructed from metal plates and sections of bar steel of any of the usual commercial forms,

To these ends my invention consists essentiallyof a sheet metal disk or plate forming the spoke portion of the wheel and having notches at its edge which receive and hold rim supporting bars arranged therein transversely of the plane of the disk and held therein against movement either circumferentially or laterally of the disk.

In carrying out my invention I prefer to use those shapes of bar iron which generally may be described'as angle bars, by which term I include T, L and other shapes. I

My invention consists further in features of construction and manner of interlocking the rim supporting bars in the disk or plate as hereinafter more particularly described.

hub parts connected by an intermediate web or spoke portion, the hub part being perforated as at 3 for the axle or for the attachment of the hub and bearings. 4 indicates 'a separate metal rim or fellyfor the wheel form a bearing for the rim and being secured to said rim by suitable means; as for instance by spot welding, while the upright or stem of the T'reinforces the bar as a support for the rim and is preferably notched as indicated at 6 to engage the plate 1 and be held thereby against lateral displacement in obvious manner by the interlockin of the bar and disk thus afiorded.

As shown in Fig. 3 the notches 7 in the edge of the disk are suitablyshaped to receive the sections of metal bar constituting the supporting brackets for the rim and when the bar is seated in said notches 7 it .low the head of the T or surface which receives the rim to be flush with the circumferential edge of the disk.

Obviously the disk may be located centrally of the supporting bars to give the same amount of-overhang of rim with respect to the plane of the disk 1. When the bar is sunk in the edge of the disk, as 'de-fl scribed, to be flush with the edge thereof, other notches 6" may be provided in the head of the T section which will engage and interlock with the disk to assist in holding the bar against displacement transversely.

Obviously further, the disk might be located to one side ofthe center of the'bar, in which case the rim would overhang the web portion of the wheel more on one side than on the other. This modification in the disshaped metal bar.

Q Lesser-e position 01" the and may be readily secured by changing the location of the notches 6, 6'. Also more than one disk'may be employed, in which case all that is neces sariy is to properly position the notches 6, 6, y

Figs. 5 to 8 inclusive 1 illustrate a modificationin which the supporting bars may be sectioned of an L-shaped or .V-

In this instance the edge of the disk or plate is suitably notched as indicated in Fig. 7, to allow the angle of the bar to enter the edge of the disk and to hold the bar against displacement circumferentially oi the disk To hold the bar against displacement trans:

As indicated in Fig. 4c, the corners of the su porting bars or brackets may be rounded ofi as at 10 to avoid thevpresence oi? prog'ect in sharp corners on the faces of the Wheel. at I claim as my invention is 1.
